Question

Q8. The displacement of a particle is given by x = square of (t-2) where x is
in m and t in seconds. The distance covered by the particle in first 4
seconds is (in m):​

Answer 1

Answer:

8m

Given x=(t−2)

2

=t

2

−4t+4

Now at t=0

x=4 m

at t=2s

x=4−8+4=0 m

and at t=4 s

x=16−16+4=4 m

Thus total distance covered at t=4s=8 units.
